What Does Rigors Look Like?

The shivering, pale face and sensation of cold in the shivery phase of rigors are similar to the shivering, pale face and sense of cold patients experience when their body temperature is actually too low (hypothermia).

What is the difference between chills and rigors?

A chill is 'a sensation of cold occurring in most fevers'. A rigor is 'a profound chill with pilo-erection associated with teeth chattering and severe shivering'.

What is a rigor episode?

A rigor is an episode of shaking or exaggerated shivering which can occur with a high fever. It is an extreme reflex response which occurs for a variety of reasons. It should not be ignored, as it is often a marker for significant and sometimes serious infections (most often bacterial).
